d93d7b9fa4 Only merge stores that aren't yet pending 
This fixes a deadlock (and possibly memory corruption, though that is
unconfirmed).  The following sequence manifests it, assuming t0
is 32-byte aligned:

    sw t0, 0(t0)
    sw t0, 16(t0)
    lw t1, 4(t0)
    lw t2, 4(t0)

Remove global fields PAddrBits and ResetVectorBits

Andrew Waterman
1f606d924f Don't perform in-place correction if there was a recent store (#988) 
Since the correction updates the entire word, the WAW hazard detection
logic is not sufficient to prevent overwriting a recent store.  So,
re-read the word after all pending stores have drained.

53dfc5e9be Remove overzealous assertion (#987) 
This assertion made sure the D$ controller was able to write the tag RAM
when a cache line was refilled.  However, it is benign if it fails to do
so: the metadata is invalid at this point, so the miss will simply happen
a second time.

This happens when resolving a tag ECC error during hit-under-miss.
